The frame l open at, its rear end, as snown in Fig. Q', to allow for the discharge o the (inst and ships produced by the cutting. CThe chain may 'oe driven from any suitable motor; the drawing showing diagrainmatieally an electric motor 7 mounted on ton of the traine i, although a coinpressed air or other prime niovei may he used. This notor is arranged with yits driv ing' shaft transverse to the main traine and utter har extension. Said driving shaft at one end is provided with a pinion S meshing` with a spur gear 9 which rotates on a suitalole stud on the machine frame and has 1 either Secured thereto or formed integral therewith e pinion l which engages with the Spur gear il secured to one end of a sleeve 1.2 rotatable in a hearing il on the ina- (':hine frame. 0n the inner end of sleeve l2 is a `Initer ,gear 14 which ingsheswith a corresponding; ,gear l on a vertical shaft l@ mounted in suitable hearings on the hed freine l. The shaft lll extends do Wnn'ardlv through the top plate el the hed frame l and arb its lower end carries a spur pinion .t7 which meshes with the master ,spur gear '18 on the shaft olt the chain driving! sprof {olt- (S, .d clutch if) is spliued to the vertu-al shaft 1G and is arranged to eonneet and dis Connectl the pinion il? to shalt, lli. This is the main clutch For stoppinl1 and starting` the cutter chain when it is desired to operate other parts of the iz'n ,tlianism Without nloving the cutting mechanism. A -quil ahle handle aetualies an arm 2l Yfor shifting said Also meshingf with the miter lgear 15 is a Com'espondingV ,Lear secured to the inner end o'lI a sleeve 24- rotatahlv mounted in hearingA in the n'iaehine trame. Extending: 'through the sleeves l2 and 94. on which the. ll, i4 and are secured is a shaft 2li to one end ol' .vhirh is secured the worin 2i' engaging! a, worin, Wheel seenred to the Vertical shaft l. The elia-t, has splined gagediwith the gear i4 the shaft 2li and Worm 27 are driven directly from the gear ll in the same direction an that ,eear revolves` hot, when said rluteh is moved toward and engaged with the rear 23 the shaft 2G and worm 27 are driven in the opposite diret-,tion 'through the intervening lniter ,Q'ear l5.

Mounted on the shaft 9 are two vvnnling drums; C'll and 35 each of which is provided with a bevel fear and one olE which, snel; 'as the lewin-most one 35, is keyed directly to the shaft Qf. -llhe other drain with its hevel Lear is loose on the shaft-and hetween the gears oi: the two drums are hevel pinions fill n'ionnted on an arm il? 'which is carried h v the shaft 2l). The pinions 8U may serve to keep the rotation ol: the two drums s vnehronous, yet permit rotation of one independent` ot' the other.

The 'feed and rguide (-ahle 43 passes around an idlersheave li on the rear inner corner of the machine trame l and is then carried to the lower winding; drum 35, panses il times around said drnni, is then carried to and around the inin'alile idler sheave 3S and thence bark to the iipper winding drinn Ell, around whim it nnntes one complete tnrn, and is then led away from 'the marhine to one of the jacks or anehor supports to preseiitliY described. third idler slleavo or 'pulleir 475 is piaoed at the front inner eorner oi the machine frame.

rThe marhine so far described is one v:norm ot :i simple machine embodying the invention. ln the operation of this apparatus` the machine frame is placed at. one corner of the room or chamber in which the ont is to he made in the position imlieated in dotted lines in 5. 'The anchor or jack lll is set up between the roof and Yfloor of the mine with its lower end just to the right of the n'iaehine frame l and at a distance from the Wall or face 47 in which the ont is to he made sl'lbstantiaily equal to the length of the n'laohinoframe. The rear end oi' the feed rope or cable 453 leading over the upper drum 34 is secured to this jack.
